l Be it'known that LJEFFREY T. FEnnns, a citizen of the United States, residing at Anderson, in the county of Madison, in the State of Indiana, have invented a certain new and useful Improvement in Apparatus for Corrugating Paper, of which the following is a description, reference beingl had to the aceompanyingdrawings, forming part of this speci- The object of my invention is to provide a simple and efficient apparatus for convert-ing plain paper into corrugated paper whose cor- .rugations shall be uniform and at an equal x 5 distance from each otherand also forsecurely aiiixiug the facing-strip of plain paper to one surface of the corrugated strip and giving it a smooth and polished appearance, forming what is commonly known as single-faced zo corrugated paper.A i

The novelty of my invention will be hereinafter set forth, and more particularly-pointed Aout in the claims. i

l In-the accompanying drawings, Figure 1 represents a side view,.partly in section, of my improved apparatus; Fig. 2,' a vertical `section upon the line 2 2 of Fig. 1, and Fig.

3 a top plan view ofthe lower heater.

'lhesame lettersol reference are used to '3o indicate like parts in the several views.

.Iournaled at opposite ends of the frame- Work are two rolls or drums A B, overavhieh pass a plurality of endless steel bands C, in the present instance three innulmber, l1`ig.2.

Secured to 'these bands transversely of the machine and parallel with the rolls`.A1 is an `iron lagging l), composed of a plurality of iron lags or bars extending transversely of the machine, parallel with 1the rollsA l5, and

4o 4 abutting tightly tog'etherside byside. These lags 1)` are iluted or corrugated longitudinally upon their outer surfaces, so that the outer surface ol the entire. lagging is corru gated transversely of the machine, as shown.

At its lower side the lagging I) is'supported by three iluted orcorrugatedrollers E, meshing wlh'the corrugations of the lagging,-and at its upper side it travelsover and is supported by a hollow steam-heated plate Fand 5o also by a chain of rollers (l, passingaround a iixed block ll.

Immediately above the block II and chain of rollers G there meshes with the corrugatious in the lagging D a small tinted or corrugated rolleruI, while lo- .cated immediately above the roller I and meshing,r therewith is a larger corrugated roller J, which is steam-heated. Supported above but resting upon the upper surface of the lagging l) above the heater F isa second -V hollow heater K, whose forward or left-hand 6o end is tapered or beveled ott', as shown, in order to extend into close proximity to the lower sideof a paste-roll L, cooperating with a paste-box M'. A flat plate N is secured in the framework transversely ofl the machine between the paste-roll L and the corrugated roller I, immediatelyabove the upper surface ofthe lagging-D. I Y

Under this consti-notion and arrangement of plain paper to be eorrugatedis led lfrom a y suitably-supported roll -Odownward beneath a guide-roller P, thence upward overa seeond guide 4 roller (2,: and, .thence downward into the corrugations inthe lagging D, and from whence it passes onward with the lagging beneath the plate 'N andpaste-'oll L,-

, by which latter pastev is applied to its upper surface. The plate N servies to hold the pa- 8o per down in the corrugations of the lagging and prevent it from springing upward and being crushed out of shape intits passage beneath the paste-roll L. AThe strip of facingpaper is led from a rollf, thence downward and forward beneath a guide-roller S, thence over asecond guidcfroller T, thence down t ward and forward around the thin forward edge of the heater K, and thence rearward beneath the latter. v The lagging D is heated 9o by its passage over the heater l?, and the small corrugating--roller I i's'heated by the larger roller J1, so that the corrugated strip O and its facing-strip R. are heated as they pass from the roller I rearward through the machine, and thc pressure and heat bt' the heater l( upon the upper side ot' the strips as they pass beneathaeeauses the facing-strip to be securely attached to -the-corrug; ed,`

them dried and firmly secured together by the time tln y emerge from the rear end el of parts the operation is as follows: The strip 7o beneath the roller I, ity-:which it is pressed 75 y strip and ironed and polished and both of roov corrugated shall be said heatei.',whence they are led. to and wound upon a storage-reel U.

The purpose of the block II and chain of rollers (of which latter there maybe several sets placed end to end lengthwise of the block, Il) is to support the lagging D at each side of the vertical plano of thecorrugatingroller I as well as immediately bencath'it, and thereby prevent the lagging fromi'ocking', as it would be liable to do if supported beneath the roller .l by a single plain roller, and also obviat-c the friction-which the pressure of the rollers I .i upon the upper side of the lagging would cause between the under side of the lagging and any fixed support, such asa forward prolongatioi'i ot' the heater F, for tbela'ggng at such point.

Itis essential that the strip of paper to b pressed into the crn'rugations of the lagging' by a roller of comparatively small diameter, so that only a few of itsteeth or corrugations can mesh with the corrueations of the lagging at the same time, in order to prevent mutilati-oriV of. the paper; but asa roller of such small diameterhut ot' su'lolent length for a wide strip of paper would -not he strong and rigid enough to exert the necessary pressure u pon the strip ot'paper the entire width of the machine the heavier and more powerful. roller .'I is provided, which is located immediately above the roller I and holds the latter in lirm engagement with the lagging.

In the present instance thc lagging; D is secured to the steel bands C by rivets, and vto accommodate the heads ot' the rivets upon 'the inner surface of said bands in passing over the rolls A li the latter yare provided with circumferentia-tlgrooves u., Fig'. 2, in line with the rows of rivets. v

In its passage over the upper surface ot' the heater F the lagging D is subjected to sliding,f friction, lo relieve which I provide the upper surface of said heater with a plurality olongitudinal gi'oo\-'es,wliich I lill with strips of Babbitt metal or brass -V,pro,jecting a sufficient distance above the surface of the heater to hold the steel bands Gand heads of the rivets out of cont-act therewith, as shown in Fig. These friction-strips can be readily removed when they become worn down and cheaply replaced with new ones.

rlo accommodate the expansion and contraction of the steel hands-J under varying,y temperatures, one ot' the rolls A l5, which support the lagging, mayne mounted in adjustable bearings, as in the case of thelroller fl' l in Fig. l., or for the same lpurpose the supporting-rollers E may be mounted in vertically-adjustable bearings to permitfmoreor less sag to the lower part of the lagging.

To prevent any particles ot' dint or other matter from falling between the lags I) in their passage over tho forward and upper side l' ot the roll A, and thereby prevent thc lags conclusr tightly together again, I provide a curved shield W for the lagging atthat point.

lagging.

A siinilarshiold may be provided at the rear .end of the machine; lmtianythingthat might fall between the lags as they pass over the upper and rear sideof the roll ll would be apt to fall out again as the lags passed around the under side of the roll.

lThe functions ot' thc heater-plato F are,

-rst, to heat the laggfiimr I), and, second, to

although I consider it preferable to employ' said hcater,as shown, for both ofsaid purposes. So, also, the functions of the upper heater I( may be performed', but in a less satisfactory manner, by a series of rollers bearing upon the u ppersu rface of the lagging, which to smoothly iron the upper surface ofthe corrugated pa! per and prevent'.- it having:r a ribby appearance should be placed diagonally or at least at a slight angle to the corrugations of the Likewise the corrugati'ng-roller I may be drilled longitudinally and steamto heat the larger roller J, the latter being,r then employed simply to support the roller I and'hold it in firm engagement with the corrugated lagging.

I am aware that it has herctoforebeen pro- 95 heated, in whiche'vcnt it willbe unnecessary IOO posed to employ ina machine of this character an endless corrugating-lagging composed of fluted or corrugated lags secured side by side at their opposite ends to the links ot' endless chains; but such construction is vnot practicable,` for the reason, among others, that the wearing of the joints ot' the chains permits sep'aration of the lags and consequent destruction of the uniformity of thccorrugations. v
